Abstract

L'invention porte sur des procédés, des systèmes et des supports lisibles par ordinateur qui peuvent servir à faciliter l'essai d'une alimentation USB inconnue qui est connectée à un dispositif CPE (équipement local d'abonné) afin de déterminer une capacité d'extraction de courant de l'alimentation USB. Le dispositif CPE peut essayer l'alimentation USB de manière à déterminer si l'alimentation USB est capable de fournir un courant prédéterminé. S'il est déterminé que l'alimentation USB n'est pas capable de fournir le courant prédéterminé, un utilisateur final peut recevoir l'instruction de brancher un PSU (bloc d'alimentation) alternatif dans le dispositif CPE, le PSU alternatif pouvant fournir le courant prédéterminé au dispositif CPE. Le dispositif CPE peut fournir une indication selon laquelle un PSU alternatif devrait être utilisé par l'intermédiaire d'un graphique fourni à un dispositif d'affichage par l'intermédiaire d'une connexion HDMI (interface multimédia haute définition) ou par l'intermédiaire d'une indication DEL à l'aide d'une ou de plusieurs DEL au niveau du dispositif CPE.
